Which corpuscles can undergo diapedesis?

Explanation

**Step-by-Step Solution:**

1. **Understanding Diapedesis**: Diapedesis is the process by which blood cells, particularly white blood cells, pass through the intact walls of capillaries to reach tissues. This is crucial for immune responses and inflammation.

2. **Identifying the Corpuscles**: The question asks which corpuscles can undergo diapedesis. The term "corpuscles" generally refers to blood cells, which include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).

3. **Focusing on Leukocytes**: Among these, leukocytes (white blood cells) are specifically known to undergo diapedesis. They are responsible for immune responses and can migrate out of the bloodstream to sites of infection or injury.
